La presente invencion se relaciona con un sujetador para su insercion a traves de aberturas alineadas en los miembros de la pieza de trabajo de manera que asegure los miembros juntos, y en particular para los sujetadores adecuados para aplicaciones de agarre corto, es decir, aplicaciones en donde el ancho total de los miembros de la pieza de trabajo que se fijan juntos es relativamente pequena.The present invention relates to a fastener for insertion through aligned openings in the members of the workpiece so as to secure the members together, and in particular for fasteners suitable for short-grip applications, that is, applications in where the total width of the members of the workpiece that are fixed together is relatively small.
Un sujetador actualmente conocido, ver por ejemplo el documento GB-A-2326 908, para su insercion a traves de aberturas alineadas en los miembros de la pieza de trabajo esta disponible comercialmente bajo la marca registrada AVTAINER, como se ilustra en las Figuras 1a a 3. El sujetador 2 conocido, comprende un pasador 6 (como se muestra en la Figura 1a), y un cuerpo 4 (como se muestra en la Figura 1b). El pasador comprende un vastago 42, una cabeza 44, y un punto de quiebre 46. El cuerpo comprende una cubierta 8 y un manguito de nilon 10. La cubierta 8 comprende una cabeza ampliada radialmente 12 en un extremo y un vastago alargado 14 que sobresale del mismo, y un orificio 16 que se extiende axialmente completamente a traves del cuerpo 4. El manguito 10, que se encuentra en el interior del vastago alargado 14 de la cubierta 8, forma un primer medio de acoplamiento, y una porcion dentada 52 que comprende una pluralidad de dientes anulares 18 en el pasador 6 forman un segundo medio de acoplamiento.A currently known fastener, see for example GB-A-2326 908, for insertion through aligned openings in the workpiece members is commercially available under the registered trademark AVTAINER, as illustrated in Figures 1a to 3. The known fastener 2 comprises a pin 6 (as shown in Figure 1a), and a body 4 (as shown in Figure 1b). The pin comprises a rod 42, a head 44, and a break point 46. The body comprises a cover 8 and a nylon sleeve 10. The cover 8 comprises a radially enlarged head 12 at one end and an elongated rod 14 protruding thereof, and a hole 16 extending axially completely through the body 4. The sleeve 10, which is located inside the elongated rod 14 of the cover 8, forms a first coupling means, and a toothed portion 52 which it comprises a plurality of annular teeth 18 in the pin 6 form a second coupling means.
Las Figuras 2a y 2b ilustran la secuencia de instalacion del sujetador 2 en una pieza de trabajo que comprende los miembros de la pieza de trabajo 20, 22. Primeramente, como se muestra en la Figura 2a, el pasador 6 se lleva hacia dentro de las aberturas alineadas 54, 56 proporcionada en los miembros de la pieza de trabajo 20, 22, mediante la aplicacion de una fuerza a la cabeza del pasador 44. Una porcion plana 78 del vastago del pasador 42 es un ajuste a presion dentro de las aberturas de la pieza de trabajo 54, 56. La Figura 2a muestra el pasador 6 despues de que se ha llevado hacia dentro de las aberturas alineadas 54, 56.Figures 2a and 2b illustrate the installation sequence of the fastener 2 in a workpiece comprising the members of the workpiece 20, 22. First, as shown in Figure 2a, the pin 6 is carried into the aligned openings 54, 56 provided in the members of the workpiece 20, 22, by applying a force to the head of the pin 44. A flat portion 78 of the pin rod 42 is a snap fit within the openings of the workpiece 54, 56. Figure 2a shows the pin 6 after it has been brought into the aligned openings 54, 56.
Subsecuentemente el cuerpo 4 se empuja, primero el vastago 14, en el extremo que sobresale del vastago del pasador 42, hasta que el extremo delantero del manguito 10 colinda con la porcion dentada 52 del pasador 6. La Figura 2b muestra el sujetador despues que se completa esta etapa.Subsequently the body 4 is pushed, first the rod 14, at the end protruding from the rod of the pin 42, until the front end of the sleeve 10 borders the serrated portion 52 of the pin 6. Figure 2b shows the fastener after it Complete this stage.
La instalacion del sujetador 2 se completa mediante el uso de una herramienta (no mostrada) para simultaneamente tirar del vastago del pasador 42 y forzar aun mas el cuerpo 4 a lo largo del vastago del pasador 42 hasta que los dientesThe installation of the fastener 2 is completed by the use of a tool (not shown) to simultaneously pull the pin rod 42 and further force the body 4 along the pin rod 42 until the teeth
18 del pasador 6 se acoplan mutuamente con el manguito 10 del cuerpo 4, y la superficie inferior 58 de la cabeza de la18 of the pin 6 are mutually coupled with the sleeve 10 of the body 4, and the bottom surface 58 of the head of the
cubierta 12 colinda con la cara exterior 72 del miembro de la pieza de trabajo 22 alejado de la cabeza del pasador 44. El vastago del pasador 142 se hala hasta que falla por la tension en el punto de quiebre 46.cover 12 adjoins the outer face 72 of the member of the workpiece 22 away from the head of the pin 44. The rod of the pin 142 is pulled until it fails due to tension at the breaking point 46.
La Figura 3 muestra el sujetador 2 completamente instalado en la pieza de trabajo para asegurar los miembros de laFigure 3 shows the fastener 2 fully installed in the workpiece to secure the members of the
pieza de trabajo 20, 22 juntos, en donde los dientes 18 del pasador 6 se incrustan en el manguito 10 del cuerpo 4. El agarre, es decir, el espesor total de los miembros de las piezas de trabajo 20, 22, se indica por S. Para proporcionar la resistencia a la traccion necesaria del sujetador instalado 2, todos los dientes 18 deben acoplarse con el manguito 10, y por lo tanto el agarre S debe ser mayor que la longitud L del vastago 14, porque el manguito 10 se encierra dentro de esta longitud, y esta longitud debe ser menor que el agarre S para asegurar que la union sea segura. Aunque el agarre mlnimo podrla reducirse mediante la reduction de la longitud del sujetador 2, esto tambien resultarla en una reduction inaceptable en la resistencia a la traccion del sujetador instalado. Una reduccion en la longitud sobre la que se acoplan mutuamente los dientes 18 con el manguito 10 resultarla en una reduccion inaceptable de la resistencia a la traccion del elemento de fijacion instalado 2.workpiece 20, 22 together, wherein the teeth 18 of the pin 6 are embedded in the sleeve 10 of the body 4. The grip, that is, the total thickness of the members of the workpieces 20, 22, is indicated by S. To provide the necessary tensile strength of the installed fastener 2, all the teeth 18 must be coupled with the sleeve 10, and therefore the grip S must be greater than the length L of the rod 14, because the sleeve 10 is enclosed within this length, and this length must be less than the grip S to ensure that the joint is secure. Although the minimum grip could be reduced by reducing the length of the fastener 2, this would also result in an unacceptable reduction in the tensile strength of the installed fastener. A reduction in the length over which the teeth 18 mutually engage the sleeve 10 will result in an unacceptable reduction in the tensile strength of the installed fastener 2.
En consecuencia, el agarre mlnimo del sujetador de la tecnica anterior se limita por la longitud de la cubierta, ya que el sujetador no puede utilizarse para valores de agarre por debajo del valor de la longitud de la cubierta.Accordingly, the minimum grip of the prior art fastener is limited by the length of the cover, since the fastener cannot be used for grip values below the value of the cover length.
Un objetivo de la presente invencion es proporcionar un sujetador en el cual el valor mlnimo de agarre no se limite por la longitud de la cubierta.An objective of the present invention is to provide a fastener in which the minimum grip value is not limited by the length of the cover.
En consecuencia, la presente invencion proporciona, en un primer aspecto, un sujetador como el reivindicado en la reivindicacion 1 de las reivindicaciones adjuntas.Accordingly, the present invention provides, in a first aspect, a fastener as claimed in claim 1 of the appended claims.
La cabeza del cuerpo puede formarse de un miembro redondeado, en donde la superficie de contacto bajo la cabeza se proporciona en una pestana anular del miembro redondeado.The head of the body may be formed of a rounded member, wherein the contact surface under the head is provided on an annular flange of the rounded member.
El primer medio de acoplamiento comprende preferentemente un manguito de nilon, y el segundo medio de acoplamiento comprende preferentemente una pluralidad de dientes.The first coupling means preferably comprises a nylon sleeve, and the second coupling means preferably comprises a plurality of teeth.

Con referencia a las Figuras 4 a la 6, el sujetador 102 de la presente invencion comprende una primera parte que comprende un cuerpo 104 (Figura 5) y una segunda parte que comprende un pasador 106 (Figura 6). El cuerpo 104 comprende una cubierta de acero 108 (Figura 4) y un manguito de nilon 110. La cubierta 108 comprende una cabeza ampliada radialmente 112 proporcionada en un extremo de la cabeza 162 y un vastago tubular alargado 114 que se extiende fuera de la cabeza 112. El manguito 110 se ubica dentro de un orificio cillndrico 116 que atraviesa la cubierta 108.With reference to Figures 4 to 6, the fastener 102 of the present invention comprises a first part comprising a body 104 (Figure 5) and a second part comprising a pin 106 (Figure 6). The body 104 comprises a steel cover 108 (Figure 4) and a nylon sleeve 110. The cover 108 comprises a radially enlarged head 112 provided at one end of the head 162 and an elongated tubular rod 114 extending out of the head 112. The sleeve 110 is located inside a cylindrical bore 116 that crosses the cover 108.
La cabeza de la cubierta 112 se forma por un miembro 124 que se extiende hacia el exterior, que tiene un primer borde anular redondeado 126 y un segundo borde anular redondeado 132, mas alejado del centro axial de la cubierta 108 que el primer borde anular redondeado 126. La forma del miembro 124 es tal que un espacio anular 130 se forma debajo de la cabeza de la cubierta 112. Mas alla del segundo borde anular elevado 132, el extremo de la cabeza de la cubierta 180 (es decir, la parte de la cabeza de la cubierta 112 que esta mas alejada del vastago del cuerpo 114) se forma por una pestana anular 134. La pestana anular 134 define una superficie bajo la cabeza 158 (que forma una superficie de contacto en la instalacion del sujetador en una pieza de trabajo).The head of the cover 112 is formed by an outwardly extending member 124, which has a first rounded annular edge 126 and a second rounded annular edge 132, further away from the axial center of the cover 108 than the first rounded annular edge 126. The shape of the member 124 is such that an annular space 130 is formed below the head of the cover 112. Beyond the second raised annular edge 132, the end of the head of the cover 180 (ie, the part of the head of the cover 112 which is furthest from the body rod 114) is formed by an annular flange 134. The annular flange 134 defines a surface under the head 158 (which forms a contact surface in the installation of the fastener in one piece of work).
El extremo de la cola 164 de la cubierta 108 se forma con una pestana que se extiende hacia dentro 136 . El manguito 110 se extiende desde la pestana que se extiende hacia dentro 136 cerca de la parte superior de la cabeza de la cubierta 112, es decir, permanece un pequeno espacio libre entre el nivel de la parte superior de la cabeza de la cubierta 112 y la parte superior del manguito 110. El diametro exterior 138 del manguito 110 es tal que el manguito 110 es un ajuste por empuje en el orificio 116 del vastago de la cubierta 114, y el diametro interno 140 del manguito 110 es menor que el de la abertura definida dentro de la pestana que se extiende hacia dentro 136 en el extremo de la cola de la cubierta 108. El manguito 110 tambien tiene un orificio, 184, que se extiende a lo largo de su longitud.The tail end 164 of the cover 108 is formed with an inwardly extending flange 136. The sleeve 110 extends from the inwardly extending flange 136 near the top of the cover head 112, that is, a small clearance remains between the level of the top of the cover head 112 and the upper part of the sleeve 110. The outer diameter 138 of the sleeve 110 is such that the sleeve 110 is a push fit in the hole 116 of the rod of the cover 114, and the inner diameter 140 of the sleeve 110 is smaller than that of the defined opening within the flange extending inward 136 at the end of the tail of the cover 108. The sleeve 110 also has a hole, 184, which extends along its length.
El manguito 110 tiene un extremo delantero 166 y un extremo trasero 168. Como se ilustra, la superficie bajo la cabeza 158 de la cabeza de la cubierta 112 esta a una distancia axial 'x' desde el extremo delantero 166 del manguito 110, y a una distancia axial ' y 'desde el extremo trasero 168 del manguito 110. En consecuencia, el extremo 180 y la superficie bajo la cabeza 158 de la cabeza de la cubierta 112 se disponen ambos en un nivel axial que es un punto medio del manguito 110.The sleeve 110 has a front end 166 and a rear end 168. As illustrated, the surface under the head 158 of the cover head 112 is at an axial distance 'x' from the front end 166 of the sleeve 110, and at a axial distance 'and' from the rear end 168 of the sleeve 110. Accordingly, the end 180 and the surface under the head 158 of the head of the cover 112 are both arranged at an axial level which is a midpoint of the sleeve 110.
El pasador 106 tambien se hace de acero, y comprende un vastago alargado 142 y una cabeza ampliada radialmente 144 que tiene una superficie lisa bajo la cabeza 176. El vastago del pasador 142 comprende una portion plana 178 inmediatamente mas abajo de la cabeza del pasador 144, una porcion dentada 152 (que forma un segundo medio de acoplamiento) que comprende una pluralidad de dientes 118 mas abajo de la porcion plana 178, un punto de quiebre 146, y una cola del pasador 148 provista con muescas de traction 150 para permitir la instalacion del sujetador 102.The pin 106 is also made of steel, and comprises an elongated rod 142 and a radially enlarged head 144 having a smooth surface under the head 176. The pin rod 142 comprises a flat portion 178 immediately below the head of the pin 144 , a toothed portion 152 (forming a second coupling means) comprising a plurality of teeth 118 below the flat portion 178, a break point 146, and a pin tail 148 provided with traction notches 150 to allow for fastener installation 102.
El diametro externo de la cola del pasador 148 es un ajuste deslizante dentro del orificio 184 del manguito, y el diametro externo maximo de la porcion dentada 152 es mayor que el diametro interno 140 del manguito 110.The outer diameter of the pin tail 148 is a sliding fit within the hole 184 of the sleeve, and the maximum external diameter of the toothed portion 152 is larger than the internal diameter 140 of the sleeve 110.
Las Figuras 7 y 8 ilustran la primera y segunda etapas de la instalacion del sujetador en una pieza de trabajo que comprende un primer miembro de la pieza de trabajo 120 y un segundo miembro de la pieza de trabajo 122.Figures 7 and 8 illustrate the first and second stages of the installation of the fastener in a workpiece comprising a first member of the workpiece 120 and a second member of the workpiece 122.
La primera etapa de la instalacion es insertar el vastago del pasador 142 a traves de las aberturas 154, 156 proporcionados en los miembros de la pieza de trabajo 120, 122. La parte lisa 178 del vastago del pasador 142 es un ajuste a presion dentro de las aberturas de la pieza de trabajo 154, 156 hasta que la superficie de la parte inferior 176 de la cabeza del pasador 144 colinda con la cara exterior 170 del primer miembro de la pieza de trabajo 120, y la cola del pasador 148 sobresale de la cara exterior 172 del segundo miembro de la pieza de trabajo 122. La Figura 7 muestra el pasador 106 totalmente insertado en las aberturas 154, 156 como anteriormente.The first stage of the installation is to insert the pin rod 142 through the openings 154, 156 provided in the members of the workpiece 120, 122. The smooth part 178 of the pin rod 142 is a snap fit within the openings of the workpiece 154, 156 until the surface of the lower part 176 of the head of the pin 144 borders the outer face 170 of the first member of the workpiece 120, and the tail of the pin 148 protrudes from the outer face 172 of the second member of the workpiece 122. Figure 7 shows the pin 106 fully inserted in the openings 154, 156 as above.

La segunda etapa de la instalacion es para posicionar manualmente el cuerpo 104, el vastago 114 primero, sobre la cola del pasador 148, hasta que el extremo delantero 66 del manguito 110 colinda con la porcion dentada 152 del pasador 106. Debido a que el diametro externo maximo de la porcion dentada 152 es mayor que el diametro interno 140 del manguito 110, no es posible insertar aun mas el cuerpo 106 a lo largo del vastago del pasador 142 manualmente.The second stage of the installation is to manually position the body 104, the rod 114 first, on the tail of the pin 148, until the front end 66 of the sleeve 110 borders the serrated portion 152 of the pin 106. Because the diameter Maximum external portion of the toothed portion 152 is larger than the internal diameter 140 of the sleeve 110, it is not possible to further insert the body 106 along the pin rod 142 manually.
Se usa entonces una herramienta adecuada para completar la instalacion del sujetador 102. Esta etapa de la instalacion no se describira en detalle ya que se conoce bien. En resumen, la herramienta aplica presion a la primera pestana redondeada 126 de la cabeza de la cubierta 112, y las muescas de traccion 150 proporcionadas en el vastago del pasador 142 habilitan el vastago del pasador 142 para halarlo con respecto al cuerpo 104. Durante el tiron del vastago del pasador 142, la porcion dentada 152 se fuerza dentro del manguito 110, provocando de ese modo que la porcion dentada 152 y el manguito 110 acoplen mutuamente. EL vastago del pasador 142 se hala hasta que la superficie bajo la cabeza 158 de la cabeza de la cubierta 112 contacta con la cara externa 172 del segundo miembro de la pieza de trabajo 122, y subsecuentemente el vastago del pasador 142 falla en la tension en el punto de quiebre 146. Los miembros de piezas de trabajo 120, 122 por lo tanto se aseguran juntos.A suitable tool is then used to complete the installation of the fastener 102. This stage of the installation will not be described in detail as it is well known. In summary, the tool applies pressure to the first rounded flange 126 of the head of the cover 112, and the traction notches 150 provided in the pin shank 142 enable the pin shank 142 to pull it with respect to the body 104. During the tiron of the pin rod 142, the toothed portion 152 is forced into the sleeve 110, thereby causing the toothed portion 152 and the sleeve 110 to engage each other. The rod of the pin 142 is pulled until the surface under the head 158 of the head of the cover 112 contacts the outer face 172 of the second member of the workpiece 122, and subsequently the rod of the pin 142 fails in tension in the breaking point 146. The members of work pieces 120, 122 are therefore secured together.
El punto de quiebre 146 esta suficientemente cerca de la porcion dentada 152, (es decir, el espacio libre entre el extremo trasero 168 del manguito 110 y la parte superior de la cabeza de la cubierta 112 es suficiente) que el extremo roto del pasador 106 no sobresale mas alla del nivel del extremo de la cabeza de la cubierta 112.The break point 146 is sufficiently close to the toothed portion 152, (i.e., the clearance between the rear end 168 of the sleeve 110 and the top of the head of the cover 112 is sufficient) that the broken end of the pin 106 does not protrude beyond the level of the head end of the cover 112.
Las Figuras 9 y 10 muestran el sujetador 102 completamente instalado para asegurar la union de los miembros de la pieza de trabajo 120, 122 juntos. La Figura 9 ilustra el sujetador 102 instalado en una pieza de trabajo que tiene un agarre relativamente grande S, y la Figura 10, un agarre relativamente pequeno, s. (La cubierta es de una longitud igual a L en ambas Figuras 9 y 10, sin embargo el pasador 6 de la Figura 9 es mas largo que el de la Figura 10)Figures 9 and 10 show the fastener 102 fully installed to ensure the union of the members of the workpiece 120, 122 together. Figure 9 illustrates the fastener 102 installed in a workpiece having a relatively large grip S, and Figure 10, a relatively small grip, s. (The cover is of a length equal to L in both Figures 9 and 10, however the pin 6 of Figure 9 is longer than that of Figure 10)
Puede observarse que, debido a que la superficie bajo la cabeza 158 de la cabeza de la cubierta 112 que contacta con la cara externa 172 del segundo miembro de la pieza de trabajo 122, se encuentra a la mitad entre el extremo delantero 166 y el extremo trasero 168 del manguito 110, parte del manguito 110, parte del vastago de la cubierta 114 que lo rodea, y tambien parte de la porcion dentada 152, se extienden mas alla de la superficie exterior 172 del segundo miembro de la pieza de trabajo 122. En consecuencia, siempre se lograra el acople completo de la porcion dentada 152 y el manguito 110 en la instalacion del sujetador 102, aun si el agarre de la pieza de trabajo es menor que la longitud de la cubierta 110. Esto se ilustra en la Figura 10, en donde, aunque el agarre relativamente pequeno 's' de la pieza de trabajo es menor que la longitud 'L' de la cubierta, se logra el acople completo de los dientes 118 en el manguito 110. En la modalidad mostrada en la Figura 10, el agarre 's' de la pieza de trabajo puede ser igual o mayor que aproximadamente la mitad de la longitud 'L' de la cubierta. .It can be seen that, because the surface under the head 158 of the head of the cover 112 that contacts the outer face 172 of the second member of the workpiece 122, is halfway between the front end 166 and the end rear 168 of the sleeve 110, part of the sleeve 110, part of the rod of the cover 114 surrounding it, and also part of the toothed portion 152, extend beyond the outer surface 172 of the second member of the workpiece 122. Consequently, the complete coupling of the toothed portion 152 and the sleeve 110 in the fastener installation 102 will always be achieved, even if the grip of the workpiece is less than the length of the cover 110. This is illustrated in Figure 10, where, although the relatively small grip 's' of the workpiece is less than the length 'L' of the cover, the complete coupling of the teeth 118 in the sleeve 110 is achieved. In the embodiment shown in the Figure 10, the grip 's' d e the workpiece may be equal to or greater than about half of the length 'L' of the cover. .
